Here's the issue: I need to pass T, which could be a string, number, boolean, object, array, or a function. The problem is I can't figure out how to handle ab("hello") in this scenario and return T as a value.
function a<T>(ab: T | ((v: T) => T)) {
if (typeof ab === "function") {
return ab("hello");
} else return ab;
}
This is the error that's been popping up: link to error https://i.sstatic.net/siE4L.png
Make sure to limit your T so that it is not strictly a function
function a<T>(ab: T extends Function ? never : T | ((v: T) => T)) {
if (typeof ab === "function") {
return ab("hello");
} else return ab;
}
